Deep mixing application

Deep mixing has proven to be a viable method to effectively improve the competency of soils in Southeast Louisiana. Both the dry and wet deep mixing methods have demonstrated that they can be used to substantially raise the insitu shear strength of the soil several orders of magnitude. All three of the deep mixing applications for Task Force Guardian required rapid construction techniques, construction sequencing, and logistical problems associated with working in confined work areas. Both deep mixing installers proved willing to meet these challenges by rapidly mobilising equipment and resources to the metro New Orleans area, quickly embarking on exploration and testing programs, and insuring quality deep mixed columns by using higher than normal binder loadings.
